To all whom z't may concern.'

Be it known that I, HENRY LANGE, va citizen of the United States,residing at Quincy, in the county of Adams and State ofIllinois, haveinvented certain new and useful In'lproveinents in Combination Coal andGas l-leaters;` and I` do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

rlhis inventionv relates to air heating stoves and furnaces, and moreespecially combination coal and gas heaters, it being the primary object of the invention to provide a stove which has in addition to theusual provision for the burnin of coal or solid fuel, novel and improvemeans for burning gas or other hydrocarbon fuel, in order that bothsolid and fluid fuels can be used either jointly or severally as desiredby the user. j

One of the specific objects of theinvention is the provision of a gasburner surrounding the fire pot and assembled with said lire pot and ashpit in a novel manner, with a simple and effective construction.

Another object is theassemblage with the burner and fire pot of aninclosing jacket for the burner to confine the products of combustiontherein so as not to pass out into the room and to permit 'said productsof combustion to circulate around the fire ot and then into the maincombustion cham er of the heater, said jacket being assembled with theburner and ash pit in a manner to be removed for purpose of cleaning orrepairs. 1

A further object `is theprovision of a grate or grid supported above theburner within the jacket in a novel manner for supporting refractorymaterial to be heated by the gas iiames so as to not only radiate heatto the walls of the jacket, but to `also give the appearance of burningcoal through the transparent panels or sides of the jacket.

A still further object is the provision lof novel, yet simple andeifective means `for conducting the products of combustion from withinthe gas combustion chamber into the interior of the stove and thenceupwardly `to pass through the usual smoke outlet, and establishing thecirculation of Specification of Letters Patent.`

prevent coal or other `fuel dumped into the l stovecfrom passing downinto the gas combustion `chamber or clogging up the gas "1t is also theobject of the invention to provide suchacombination of coal and gasheater `comprising a comparatively `simple construction ofthe componentelements and a simple and practical combination and assemblage thereof,in order that the parts can be readily assembled and taken apart, andproviding for a thoroughly practical and serviceable structure.

With the foregoing and other objects in view which will be apparent asthe description proceeds, the invention resides in the l constructionand arrangement of parts here- `inafter described and claimed, `it beingunderstood that changes can be made within the `scope of what is claimedwithout departing from the spirit of the invention.

` The invention is illustrated inthe accomj panying drawings, wherein :k

\ Figure Il` is a vertical section taken from the front to the rear,portions being shown j in elevation.

` Fig. 2 is a vertical section taken from side to side at right angleswith the plane of section in Fig. 1.

Figs. 3, l and 5 are horizontal sections taken on the respective sectionlines 3-3, 4-4 and 5-5 of F ig. 2.

The stove or heater, for-the purpose of burning coal or other fuel, isof about the usual construction, and includes the ash pit 1 on which ismounted the fire pot 2, with a l suitable grate 3 at the bottom thereof,said .fire pot comprising a ring or annular wall, the upper edge ofwhich is provided with an outstanding flange or rim` 4. The' upstanding`drum o1' shell 5 of the stove is supported by the fire pot 2, and isprovided with a suits able fuel door 6, and a top 7 provided with theusual smoke outlet or collar 8 through which the products of combustionpass, this outlet or collar 8 being1 usually at the rea-r and the door 6at the front of the stove. The kstove so far described is ofconventional form forburning solid fuel in the usualway.

In .order that gas or other fluid hydrocar- Vwhich the gas is suppliedto'pass into the annular chamber of the burnerv and out through theapertures in the top. This `burner 9-is placed onk the ashpit, and issupported thereby, andi thel ire pot-is then seated on the ash pitwithin the burner, in

said-,burner beingspacedfrom .the wall of the iref'pot, to. permit theair to flow upw-ard-lywithin the burner to the iiames, so to facilitate,combustion of' the gas. The ribs .lOfnot :only space the burner abovethe ash pitybut .alsospace it .from the wall of the Y re pou-sothatadesired amoimt ofyair. can

enter the gas combustionchamlber from withinftheburner.; The wall of thetire pot `2-has lugs 11.that.seat,dovvn on theri-bs 10, in order that.the'burner will be held down securelywiny pl-aeeon the'ash pit 1, bythesecuring;.1neans12:which fasten the tire pot 2 dow-mon the ftop. or.Vshoulder of the ash pit l.

Ajacket 13, extends from the outer side ot thei'burfnerl 9 .totheflangel of the lire pot, andv provides-1an inclosed air combustionchamber above the-burner' surrounding the iireipot; Thisfj acket 13 ispreferably bulged oi-itwfardly or of -swell formation, for purpose ofornate appearance, and is composed ofif'fronai. rear andV sidel sectionseach of whichinclude outer and inner longitudinally andtransverselycurved frames 14 and 15, re-

with transparent panels 1G clamped therebetween, andv composed ot micaor similar material.v These frames 14 and 1'5A are provided withopeningsthroughout i exposing the panels 16 and fnot onlyv permitting the heattopass'4 through but also perf mit-ting the Haines to be seen through thesidesof the walls of the'jaeket. Although thereanjacket sectionisshownof the same construction asthe side and trent sections, it

Y can beet-a solid plate of metal, especially ivhenfthe rearfof thestove isnot. exposed to view, Ther ends-,of the-jacket sections tit,togethery and overlap, as seen in Fig. 3, and

thus extendicompletelyaround the -irepot in y annularform, lThelower-edges of the :j acket frames 14 are provided with downwardl'yeX- tendingylugs 17 that enter `apertured ears 18 projecting'outwardlyfrom the outer, side'cf Itheburner. '9,ftheploweredges of the jacket.sections beingthuSuppQrtedf from the burner 9, while their upper edgesare secured to the ange or rim 4 of the tire pot.

Thus, the upper edges of the frames 14 have lips 19 to bear against theedge of the liange 4, and said lips of the side and rear jacket sectionsare secured to said iiange 4 by means .of bolts 20 or the like, whilethe front jacket ears 18, thereby permitting said sections to be swungagainst the iiange 4 and secured, and thecatch 21 permits-the frontjacket section to be released and removed when access is wanted. intothe gas combustion chamber. This jacket provides anannular combustionchamber above the burner9 around the lire pot, which, .can contain lumpsof refractory ,materiah so, as to. bey hea-ted red hot by the flames,for not only giving heat, but to also give the appearance of burningcoal.

When such refractory material is used, arcuate grates or grids 22 aredisposed above the burner 9 within the jacket 13, and are arranged endtoend so as to extend completely yaround the-tire pot over the burner 9.These 'grates or grids 22 will support the lumps or pieces of refractorymaterial above the burner 9, and in order to support said grates orgrids above the burner, the outer edges of said grates have outstandingflanges 23 seated on lugs 24 projecting inwardly from the inner frames15 of the jacket 18, while the gra-tes 22 are provided Vattheir inneredgeswith downwardly extending lugs 25 seating on the burner 9. Thesegrates or grids 22 can be readily inserted and` removed, as they aresimply seated on the-jacket 13 and burner 9.

Tn order to-conduct the products of combustion from. within the gasburner into the stove, the wall of the tire pot 2 is provided'1 atopposite sides and near its upper edge with series of openings 26,permitting the gas toIpass-rom the gas chamber within the jacket 13inwardly through said openings. Thus, the products of combustioncirculatingmwithin the gas chamber surrounding the lire pot can liowinwardly through the openin gs 26 to ultimately pass through thc smoke Youtlet 8.0i2 the stove, without a special outlet for the products ofcombustion from the burntgas. In other words, the products of combustionfrom coal and gas both pass out through the usualsmoke outlet 8, insteadol there being separate outlets for coal and gas.

Asa means for-conducting the products of combustion fromtheopenings 2G,there is provided upon the interior of the lire pot 2 and drum orshell 5of the` stove means for that purpose, including a vertical lue 27 atthe=back,.of the stove, andhorizontal tlucs 28` at; the oppositesides.These iues 27 and 28 each f consist lof a -metal plate, preferablyLele-,51e

of cast metal, and theue 27`f"is disposed vertically adjacent to thedrum` 5 parallel therewith and is curved transversely, as'seen in Fig.fl, according to `thecurvature of the drum 5, while the iues 28 arecurved longitudinally concentric with .the l, drum `5, as seen in Fig.3. Thelower edges of the fiues `27 and 28 have portions 29 seating on anannular seat or shoulder 30 with which the wall ofthe fire pot isprovided on the inte rior thereof immediately below thehorizontal planeof the openings 26. The side or vertical edges of the `flue 27 `areprovided at thelower end of said flue with iangesvl overlapping therearends of the fluesv28 so that the rear ends ofl the side flues 28`corninunicate with the rear vertical flue 27, and

`this also holds the rear ends ofthe side iiues in place againsttherearof the Vdrum and fire pot;V `The flue 27 has its verticalside edgesextending rearwardlyyas lat 33, and contacting with the drum,5,"`andsaid flue has side openings 34" at its lower endiregistering with therearends of the flues 28, and said flue 27A also has side openings 35 atits upper end discharging the lprbducts of combustion toward theopposite sides. The flue 27 is below the smoke outlet 8, so that theproducts of combustion in passing through the openings 35 will then passupwardly through the smoke outlet, and these openings 35"aresufficiently high up so that coal or other fuel dumped into the stovewill not" fall down through saidopenings. `The forward ends of the iiues28 are curved toward and shaped, as at 32, to closely fit the fire potand drum. The flue 27 has recessed portions 36 extending rearwardly andfastened by"`m`eansof bolts 37 or the like to the back ofthe drum 5,thus clamping said Hue thereto, and the flues 28 are provided withsimilar recessed portions 38 fastened by means of bolts 39 or the liketo the drum 5 near the forward ends of said fines 28`and front wall ofthe drum. This secures theforward end of the iiues 28 to the drum whilethe Arear ends are yheld thereto by, theflanges 3l of the flue 27. Theupper edges of the lues 28 are curved `toward and contact with the drum5, as at 4-0, to retain the products ofcombustion in said fines andprevent coal or ashesfalling downinto said flue,` and theupper end` ofthe flue 27 is also curved toward and in con tact withtheback of thedrum, as at 4L Thus, any coal, ashes or other particles lfall-` ing onthe flueswill be shed downwardly into the fire pot. l

s When the gas burneris the products of combustion after circulating inthe gas combustion `chamber within the jacket 13 around the fire pot 2,will pass through the openings1 26 into the'iues 28 and will circulaterearwardly and pass upwardly within the flue 27 and outthrough theopenings35 to the smoke outlet 8. "'lhus,` the is claimed as new is`portions so thatthe lire productsof combustion fromthe gas burner willcirculatetfrom the gas combustion chamber into" the stove, beingconfined within the flues 28 and 27 to pass along the wall of the drum5, thus giving Iout additional heat through said drum and ultimatelypermitoutletpassages of the gas combustion chamber are locatedwithinthedrum or shell of the stove, and the arrangement is such that it will notinterfere with theburning of coal. Such `Ventilating means is simple,embodying onlythe three plates or flues 27 and 28which `can be readilyapplied Within the stove. `The burner construction isalso equally simpleon theexterior of theflre pot, andthe entire construction provides forpractical manufacture `and use.
